Looking to rent a room in my favorite city Barcelona

I love Barcelona so much that I want to stay here. I'm looking to rent a room in somebody's apartment. 

I'm a 27-year-old from Estonia. For some time I've been just a free traveler, enjoying life. Before that I've always been a freelance teacher/coach/trainer.

I can pay a couple of months' rent up front if necessary and also I can teach English or Russian (or Estonian but you shouldn't want to learn Estonian) or public speaking presentation or argumentation skills.

Please contact me on Whatsapp if you have an offer or if you have any ideas at all :)
